Or HaChaim on Numbers 7:48/אור החיים על במדבר ז׳:מ״ח

1 אלשמע בן עמיהוד. Rabbi Meir and Rabbi Yehoshua ben Korchah are quoted in Tanchuma on our verse as saying that the name Elishama suggests that whereas "Joseph listened to the commands of G'd, he did not listen to the command of his mistress to sleep with her. He did not make common cause with the wicked." Joseph did not desist from sinning because he was not tempted but because he was obedient to G'd's imperatives as he pointed out to the wife of Potiphar when he described giving in to his urge as a sin against G'd (Genesis 39,9). This is what is meant by Elishama, i.e אלי שמע, "he listened to Me." Our sages in Sotah 36 explained that at the crucial moment he had a vision of the face of his father. Clearly, this is a reference to a divine image which resembled the face of Jacob. After all, his father was in Canaan and had no inkling of what temptation his son faced at the time not even knowing that Joseph was still alive. What Joseph beheld in the vision was what is known as אביר יעקב אלוקי ישראל. When the sages in the Midrash spoke of the wicked in the plural, they may have referred to many similar temptations that Joseph withstood successfully. The reason the same idea occurs a second time in the name of the father of Elyasaph, i.e. עמיהוד is to hint what the Torah told us in that verse in Genesis that he did not listen to Mrs Potiphar who requested that Joseph agree to be physically close to her. Joseph preferred to remain close to G'd, i.e. עמי הודו.
